The radial variation of the solar wind turbulence spectra near the kinetic break scale from Parker Solar Probe measurements
S. Lotz, A. E. Nel, R. T. Wicks +7
In this study we examine the radial dependence of the inertial and dissipation range indices, as well as the spectral break separating the inertial and dissipation range in power d…
The essential role of multi-point measurements in investigations of turbulence, three-dimensional structure, and dynamics: the solar wind beyond single scale and the Taylor Hypothesis
W. H. Matthaeus, S. Adhikari, R. Bandyopadhyay +49
Space plasmas are three-dimensional dynamic entities. Except under very special circumstances, their structure in space and their behavior in time are not related in any simple way…
Relativistic electron precipitation by EMIC waves: importance of nonlinear resonant effects
Veronika S. Grach, Anton V. Artemyev, Andrei G. Demekhov +7
Relativistic electron losses in Earth's radiation belts are usually attributed to electron resonant scattering by electromagnetic waves. One of the most important wave mode for suc…
